Abstract
We present measurements of triple gauge boson coupling parameters usin g data recorded by the OPAL detector at LEP2 at a centre-of-mass energ y of 172 GeV. A total of 120 W-pair candidates has been selected in th e q (q) over bar q (q) over bar, q (q) over bar l (v) over bar(l) and l (v) over bar(l)(l) over bar'v(l') decay channels, for an integrated luminosity of 10.4 pb(-1). We use these data to determine several diff erent anomalous coupling parameters using the measured cross-section a nd the distributions of kinematic variables. We measure alpha(B phi)=0 .35(-1.07)(+1.29) +/- 0.38, alpha(W phi)=0.00(-0.26)(+0.30) +/- 0.11 a lpha(w) = 0.18(-0.47)(+0.49) +/- 0.23, Delta g(1)(z) = -0.03(-0.37)(+0 .40) +/- 0.14, Delta kappa(gamma)((HISZ)) = 0.03(-0.51)(+0.55) +/- 0.2 0, and Delta kappa = 0.03(-0.46)(+0.49) +/- 0.21. Combining the alpha( W phi) result with our previous result obtained from the 161 GeV data sample we measure alpha(W phi) = -.0.08(-0.25)(+0.28) +/- 0.10. All of these measurements are consistent with the Standard Model.
